Phonological disorders treatment effect with a stimulability and segment complexity strata model with speech intervention software (SIFALA)

ABSTRACT This paper focuses on the effect of the Strata Model based on Stimulability and Segment Complexity combined with the use of Speech Intervention Software on phonological disorders treatment. A case study was conducted with four subjects aged between 4:10 and 6:7, both males and females, with phonological disorders. All subjects were assessed for phonological system, stimulability, stomatognathic system and hearing screening. The therapeutic model was based on a mixed approach, wherein different models, procedures and strategies were combined, adapted and created. Each subject was treated with one of the four strata proposed in the model. The use of Speech Intervention Software was aimed at motivating the children by means of an interactive, lively and playful code. An analysis was made of data on subjects' phonological system and number of correctly produced consonants, both before and after therapy. The Chi-square test was used with a level of significance at 5% (p
